Glass gem showing camel, loaded with a pack (Roman, AD 100–300)
Large animals are good at pulling heavy objects, especially machinery used in farming, such as ploughs.
Animals which can pull carts are also necessary for taking produce to a place where it can be sold, and for carrying people. Before the age of the petrol engine if you wanted to get around faster than human walking pace, you had to be pulled by a beast – most often a horse, ass or donkey.
Camels can travel long distances in harsh conditions with heavy loads, making them ideal for transporting goods.
